  var tally = 0;

  jQuery(function () {
    function loopClickEmToRunEm() {
      setTimeout(function () {
        jQuery('#button_1').trigger('click');
      }, 0);
      setTimeout(function () {
        jQuery('#button_2').trigger('click');
      }, 3000);
      setTimeout(function () {
        jQuery('#button_3').trigger('click');
      }, 6000);
      setTimeout(function () {

        console.log(tally++);
        loopClickEmToRunEm();

      }, 9000);
    }
    setTimeout(function () {
